[mpich-discuss] Problem about MPI Program

[Jayesh Krishna]

Hi,
 Which version of MPICH2 are you using (Which OS ?) ? Can you send us a test program that fails ?

Regards,
Jayesh

Subject: Problem about MPI Program


hi, I'm an undergraduate from China. Recently I've met some problems about mpi running between machines.I use MPI_Isend and MPI_Irecv to communication while MPI_Waitall to test.It is successful 
when i ran the program on a single machine or different machines with sending small message.But when i was sending message which is about 100k,it is failed.We received the message"MPI_Waitall (count=12,req_array=..,status_array=..) failed, read from socket failed ".I wonder if there are not enough message cache area.But how to set this area's size.Please help us.
